I think journalists perhaps do need to proofread a bit more when using they pronouns for a specific person but referencing others too.
Sam, who is non-binary, performed for a crowd of both Republicans and Democrats, with the bill having been supported by members of both sides, and was accompanied by backing singers and a keyboardist. Needless to say, they absolutely smashed it.
Is that saying Sam plus the backing singers and keyboardist smashed it, or just Sam? The first would be nice, but I suspect they mean the latter.
Or
Lovato and Ehrich dated for around seven months before breaking up in September 2020.
They came out as non-binary in May 2021 after “a lot of healing and self-reflective work”.
Both of them? Saying "Lovato came out..." would be much clearer.
Yes, context helps, but not in every case.
